Action required: IBC assets on Sei will become inaccessibleIf you hold USDC.n (USDC via Noble), USDT.kava (Kava USDT), Wormhole-bridged tokens, or any other IBC asset on Sei, you must swap, migrate, or bridge out before the governance proposal to disable inbound/outbound IBC transfers passes and is activated to avoid permanent loss of access. After this, Sei will no longer support IBC bridging of assets from Cosmos-based chains to and from Sei Network.Consult the SIP-03 Migration Guide for the full list of affected assets, required actions, and supported routes.For USDC.n specifically, see: Holders of USDC.n Need to Swap or Migrate.
